Bus & Recreational Vehicle
Dalsin Industries is a key player on the team redesigning transit bus doors, panels, access hoods, and skin sets for the leading Transit Bus builder in America.
#1 TRANSIT BUS BUILDER. Dalsin’s OEM customer has delivered over 20,000 buses to approximately 200 US customers – more than any other manufacturer.
Dalsin’s engineering team was tasked with the challenge to redesign a product family of transit bus doors and skin panel sub-assemblies in an effort to cost reduce and improve the fit and functional rigidity of the panels across the entire product family. The original design intent of the aluminum panel subassemblies was based on an outer aluminum sheet skin with numerous custom machined tube members welded into position on the inside surface of the panel.
The Dalsin team engaged on the project, and quickly analyzed opportunities to incorporate design strength vs. gauge strength; automated manufacturing methods of the Trumpf Trupunch 5000 punching center and Salvagnini P4 panel bending workcenters; streamlined riveted with structural adhesive assembly techniques replacing the welded construction of the original design.
Together the bus company and Dalsin, through a rapid and collaborative initiative, successfully achieved cost reductions and significant improvements through bill of material line item reductions (resulting from P4 formed geometries creating torque box effects around the perimeter of the panels), assembly processing and lead-time reductions. The product family has proven to benefit from Dalsin implemented enhancements to the structural, mechanical, and powder coated cosmetic performance of the product family. The end result is better bus panels at lower costs in less time.
